This invention relates broadly to fuse pullers and more particularly tofuse pullers adapted for use in connection with overhead line insulationand the object of the invention is to provide an may be readily mountedon the puller to guard the operator against shock when working in wetand damp weather.

Briefly the invention consists in the provision of an insulator whichmay be readily associated with the fuse puller and is simple andeconomical in construction.

The invention together with its objects and advantages will be bestunderstood from a study of the following description taken in connectionwith the accompanying drawings wherein:

Figure 1 is a side elevational view of a fuse puller having theattachment associated therewith.

Figure 2 is an enlarged elevational view of the attachment, certainparts being broken away and shown in section.

Figure 3 is a top plan view of one section of the clamp forming part ofthe invention.

Figure 4 is a side elevational view of said one section.

Figure 5 is a top plan view of a complemental section of the clamp.

Figure 6 is a side elevational view thereof.

Figure 7 is an elevational view of a cone forming part of the invention,and

Figure 8 is a sectional view taken substantially on the line 88 ofFigure '7.

Upon referring to the drawings it will be seen that the attachment isshown applied to a well known type of fuse puller, the same embodyingthe subject matter of Patent No. 1,876,892 and including among otherparts a fuse puller or clamp indicated generally by the referencenumeral 10 and provided with an internally threaded socketed body 11;and handle 14 which has its upper end engaged in a socket 15 and securedtherein as at 16. The socket 15 is provided on one end with a stud orpost 17 which, when the attachment forming the subject matter of thepresent invention is not used, is adapted to be screw threaded into thesocket 11 of the fuse puller or clamp 10. For the handle 14 there may bealso provided suitable extensions 18 that are provided with sockets 19for receiving the ferrule equipped end 20 of the handle 14. The ferrule20 and the socket 19 are provided with suitable inter-engaging means 21,22 for locking the end 20 within the socket 19.

The insulation attachment forming the subject matter of the presentinvention is indicated generally by the reference numeral 23 andincludes a body 24 of porcelain or other suitable material which ispreferably of the shape shown being provided at the top thereof with ahead 25 and at the bottom thereof with a depending boss 26 that has anaxial threaded tapered socket 27 formed therein and into which is screwthreaded the threaded end 28 of a coupling cone 29. At its largest endthe cone 29 is provided as shown in Figure 8 with an axial threadedsocket 30, which when the attachment is to be used, is adapted to havethreaded therein the aforementioned stem or post 17.

The head 25 of the porcelain or body 24 is provided with acircumferential groove 31 for accommodating the complemental sections32, 33 of a two-part clamp forming part of the invention. As will benoted the complemental sections 32, 33 of the clamp are substantiallysemi-circular and one of the sections, in the present instance thesection 32 has the ends thereof provided with threaded studs 34 adaptedto be engaged with bosses 35 provided on the ends of the clamp section33. Wing nuts or the like 36 are engaged with the pins 34 for securingthe sections 32, 33 clamped about the head 25 and within the groove 31.

The clamp also includes a cross piece 37 that is integral at one endwith the intermediate portion of a clamp section 32, and at its free endis provided with a threaded pin 38 adapted to pass through an apertureprovided in the upper end of angular lug 39 provided on an intermediateportion of the clamp section 33. A wing nut or the like 40 is screwthreadedly engaged with the pin 38. The cross or bridge bar 3'7 isaccommodated in a groove suitably provided at the top of the head 35 andhas formed integrally therewith and intermediate its ends a verticalpost or stem 41 that is threaded and is adapted to be screwed into thesocket portion 11 of the clamp 10 so that the parts will then be held inassembled relation shown in Figure 1.

From the above it will be apparent that with the attachment 23 thusinterposed between the clamp 10 and the handle 14 the fuse puller can beused during inclement weather with very little or no danger to theoperator. During dry weather and when it is not desired to use theattachment 23 the same may be readily removed by unscrewing the stem 17from the socket of the cone 29, and the stud or stem 41 from the socket11. With the attachment thus removed the stud 1'7 may be threaded intothe socket 11 and the puller used in the usual manner.

Having thus described my invention, what I claim as new is:

1.VA device of the character described comprising a two-part clamp eachpart of wlfich includes a substantially semi-circular part adapted toembrace an insulator, one of said parts at the ends thereof beingprovided with threaded studs, and the other of said parts at its endsbeing provided with apertured bosses axially receiving said studs tosecure the parts about the insulator, the first named part of the clampbeing also provided with a cross bar having a free end equipped with athreaded stud, and the second named part of the clamp having anupstanding apertured lug to receive the threaded stud of the cross bar,

a nut engaged with said stud for securing thev same engaged with thelug, and said cross bar intermediate its ends being also provided withan upstanding threaded post adapted to be screwed into the socketportion of a fuse clamp.

2. A clamp for connecting an insulator and fuse clamp together andcomprising a pair of complemental sections adapted toembrace aninsulator, inter-engaging means on the sections at the meeting endsthereof for connecting said sections together to secure the same aboutthe insulator, one of said sections having a cross bar integral at oneend with said one section and having a free end provided with a threadedstud, and the other of said sections having an angular lug apertured toreceive said stud, a nut engaged with the stud to secure the sameengaged with the lug, and said cross bar intermediate its ends beingprovided with a threaded post for threaded engagement with the socket ofa fuse clamp.

'3. An attachment for connecting a fuse puller clamp with its handle andcomprising an insulator including a body, a head, a reduced neckconnecting the head and body and a threaded socket in the end of thebody opposite to said head, a clamp embracing the neck and including across bar extending across the head of the insulator and providedintermediate its ends with a threaded post for screw threaded engagementwith the socket of t e fuse clamp, and a coupling cone having threads atone end for screw threading said end into the socket of the insulator,and provided in an opposite end with a threaded socket for screwthreaded reception of one end of said handle.
